Enter the installation of wiring module plc

input module plc end if set to "always check line" status input module input end of the line (away from the module side) must be parallel with the termination resistor programmable logic controller (plc) suppliers  module inputs If set to "normally closed check line" Status Input Module Input end of the line (away from the module side) must be a plc analog output module in series termination resistors. When the module is active output, active output terminal should be parallel termination resistor 4.7kΩ, and IN4007 series with a diode.
